to be modified during system operation

• All modules are hot-swappable with an FCN-100.

 GENERAL

This document describes the system configurations,

development/maintenance, software configurations,

network and specifications, for two types of

autonomous controllers in the STARDOM: FCN with

NFCP100 CPU module and FCJ.  (FCN is an acronym

for field control node, and FCJ for field control

junction.)

Notation in this document:

• The term “FCN” refers to the module consisting type

autonomous controllers.

• The term “FCN-500” refers to the autonomous

controllers with NFCP501/NFCP502 CPU module.

• The term “FCN-100” refers to the autonomous

controllers with NFCP100 CPU module.

• The term “FCN-RTU” refers to the low power

autonomous controllers with NFCP050 CPU module.

• The term “FCJ” refers to the all-in-one type

autonomous controllers.

FCN-100 is a controller module consisting of CPU, I/O,

and other modules as necessary.  It supports a variety

of I/O modules, provides a highly reliable system with

duplexed power supply, CPU and control network

options as well as superb scalability.

For hardware details, refer to FCN Autonomous

Controller Hardware (FCN-100), GS 34P02Q12-01E.

 CONFIGURATIONS

l    System    Configurations

FCN-500 is locally mounted controllers to allow diverse

systems to be configured according to the individual

users’ work sites; however, the possible system

configurations can be broadly divided into three types:

• A system consisting of a standalone FCN-500

• A system in which FCN-500s are connected to

each other through the control network and perform

interlinked actions (up to a total of 15 FCNs and FCJs

can intercommunicate with one FCN/FCJ).

• A system in which one or more FCN-500s are

interlinked with VDS, FCN/FCJ OPC Server or FAST/

TOOLS.

VDS and FCN/FCJ OPC server, FAST/TOOLS can

be connected up to 8 units in total. The FCN/FCJ

OPC server counts as 2 units because the DA server

and AE server operate. The FAST/TOOLS with

duplexed network counts as 2 units.

Development    and    Maintenance    of    FCN-500

A PC/AT-compatible computer is used for development

and maintenance of applications for an FCN-500.

Resource Configurator is a tool program to be installed

in the computer used for maintenance, and is used to

make the FCN-500 hardware settings.

The user can access FCN-500s via a Web browser

from a PC to make detailed settings for the network

and so on, and to perform maintenance operations

such as database backup and restoration.

Logic Designer is a tool program for the development

of control applications (IEC 61131-3) for an FCN-500.

Logic Designer requires a license to run.
